If you ever wanted to find out what satellites might see when they pass over your home, you can use Internet mapping services such as Google, Bing and Yahoo. These companies compiled satellite imagery from around the globe and stitched it together to provide a bird's-eye view of almost eve...
These objects generally circle from north to south, over Earth's poles, and take about 12 hours to make one complete trip. Polar-orbiting satellites also pass over the planet's poles on each revolution, although their orbits are far less elliptical. The polar orbit remains fixed in space as...
You can also see the moons of Jupiter (Galilean satellites) -- Io, Europa, Callisto and Ganymede. The moons orbit Jupiter in changing positions each night, and they are interesting to watch over the course of many days. In a large telescope (8- to 10-inch or 20- to 25-cm reflector)...
The best time to view the Quadrantids is between the late hours on Jan. 2 to just before the break of dawn on Jan. 3. — when the radiant of the shower is ascending the northeastern sky. This year,the moonwill be 9% illuminated at the time of the shower's peak. To calculate sun...

GPS can provide highly accurate absolute location information, typically within a few meters. However, accuracy may vary based on factors such as the number of visible satellites, signal interference, and the quality of the GPS receiver.

Today, satellites regularly provide ultraviolet images of solar storms.COLOR AND THE AURORA A sampling of aurora colors from some of the photos I’ve taken. The atmospheric gas determines the color at altitude (mainly atomic oxygen and nitrogen), its electrical state, and the energy of the ...
Sarah Connor was concerned primarily about GPS signals. At first glance, that’s logical; we use satellites to determine the exact location of a device. In reality, however, things aren’t that straightforward. Can you be tracked by GPS?
We've all heard of satellites and radar, but you might not be familiar with surface maps. Surface maps are used to view areas of low and high pressure. Surface maps indicate certain weather components like areas of high pressure or low pressure. High pressure brings us good weather, ...
